The colossal case is 51mm in diameter without counting the impressive crown cap and pushers. It is undeniably based on replica omega Seamaster Special Edition watches military styling with a protruding, protective bezel, five visible fastening screws, and a matte satin finish.
Italo Fontana has very well figured out how to design big watches. U-Boat watches are between 45mm and 55mm in diameter and even reach 65mm in the particular case of the U-1942. One thing that has not been associated much with these gargantuan timepieces, however, are complications. Showing that they are at the height of more traditional replica omega Seamaster Special Edition watches watchmakers to produced complicated watches, U-Boat released the U-51 Rattrappante complicated model.With a complex system of levers, springs, and pinions, the rattrapante or split-second chronograph movement is one of horologys finest mechanisms. Its function is to allow the user to mark a time measurement without stopping the ongoing timer. This is done by overlapping two independent seconds hands. After starting the chronograph as usual, a third chronograph pusher can be used to stop one of the overlapping second hands and allow the user to take a reading. This can be used for timing lap times for instance. The English replica omega Seamaster Special Edition watches name for this type of chronograph is derived from the action of splitting the hands. Once the button is pushed again the hand that had stopped catches up to the primary chronograph seconds hand instantly. This gives the function its French name: rattrapante.Mostly you will find such fine mechanisms in more traditional and elegant watches, but the U-51 is nothing like these.
